Your copy of the DA 17-70 is way out of focus calibration if not downright broken (or just a horrible copy). I have that lens and it's sharpness is nowhere near what your images are unfortunately displaying.

A couple of questions that will help people give you the best answers:
1) Are you looking for a zoom lens or a prime which will usually be sharper than any zoom?
2) Did you try to micro-adjust the focus on the DA 17-70? (for a zoom, I find it quite sharp with excellent contrast)
